JOHN B. NORTON, OF PHILADELPHIA, PENNSYLVANIA.

-I aiLT-FASTELNER.

SPECIFICATION forming part of Letters Patent No. 292,173, dated January 22,1884.

Application led June 5, 1883.

My invention relates to belt fasteningsV wherein a joining-plate is used providedwith a series of pins, which engage the meeting ends of the belting, said pins being upset to hold in the belting material. Fastening devices of this description heretofore made have been substantially rigid, and therefore could not be used successfully on smallpulleys, for

the reason that the fastening-plate strikes the pulley tangent to its circumference and ballots or hammers the pulley.

The object of my invention is to overcome this objection and produce a belt-fastening plate which will conform to the curvature of the pulley and pass smoothly and evenly around it.

My invention consists in an elastic or nexi- ,ble steel plate which covers the meeting edges ofthe belt, in combination with two narrow heavier plates provided with teeth Or projec- 35ftions to be upset, one of which is applied through the flexible plate and each end of the belt, thereby securing the flexible plate and the ends of the-belting together in a yielding but substantial joint.

Fig. 4 shows modifications (No model.)

steel or any other desirable material, which,

will yield to the curvature of the pulley as the belt passes around it. 'Ihe ilexible plate B is secured to each end of the belting by means of two independent plates, O O', provided with teeth a, a, which are passed or driven through the flexible plate B and the ends A A ofthe belt. The teeth a ct are then upset in the usual manner, thereby securely fastening the belt ends together in such a manner that the ilexible plate yields to the curvature of the pulley, and the heavy narrow plates do not injuriously affect the travel of the belt.

If desirable, there may be rivets b b put through the extreme ends of the flexible plate, as shown; but this may be omitted or some similar fastening substituted for the rivets without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a belt-fastening device, the exible plate B, in combination with two independent plates, C C', provided with teeth aa, all constructed and arranged substantially as described.
